Statistiques de Vent de Agnes Waters, moyennes sur Décembre depuis 2006
This image describes how commonly and how strongly the wind blows from different directions through a typical December. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 2457 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Agnes Waters, located 27 km away (17 miles). There are not enough recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Agnes Waters blows from the ENE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Agnes Waters. On the other hand, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average December, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 4% of the time (1 days each December) and blows offshore just 6% of the time (2 days in an average December). During a typical December wind stronger than >40kph (25mph) was predicted for only a single days at Agnes Waters
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
